Just to clarify - even if the SIM goes into a hub, there needs to be a (phone) number attached to the SIM card. That's the "address" where the data is delivered to.
When I set up my MF928 I had to manually input the APN info for Public Mobile (plug into computer and log into the "website" as indicated in the start-up leaflet, I don't have it handy right now, sorry...) It has worked flawlessly ever since. (Except that I had to put the SIM into a phone to receive the 6 digit code for setting up my account again on Wednesday. This SMS or voice only on initial sign-in is SOOO stupid, get that e-mail option in there from the get-go, PM!!!)
The reality is that customer service agents of any brand will only help with set-up trouble shooting if the device has been bought from them. Years ago a friend of mine bought the exact same model MiFi as the one in the Bell line-up at the time, just that he got it unlocked online. Bell refused to help him setting it up with a Bell SIM. Public Mobile works on any device as long as it has the proper bands and is unlocked / locked to Telus or Koodo but you will need to be willing to do your own trouble shooting with the help of us community members who are customers just like you who are willing to share their experience. (There are some limitations when it comes to VoLTE, but that's a different story.)
